You administer a Microsoft SQL Server 2012 server that hosts a transactional database and a
reporting database. The transactional database is updated through a web application and is
operational throughout the day. The reporting database is only updated from the transactional
database.
The recovery model and backup schedule are configured as shown in the following table:
The differential backup of the reporting database fails. Then, the reporting database fails at 14:00
hours.
You need to ensure that the reporting database is restored. You also need to ensure that data loss is
minimal.
What should you do?
A.
Restore the latest full backup, and restore the latest differential backup. Then, restore the latest
log backup.
B.
Perform a point-in-time restore.
C.
Restore the latest full backup.
D.
Restore the latest full backup, and restore the latest differential backup. Then, restore each log
backup taken before the time of failure from the most recent differential backup.
E.
Restore the latest full backup. Then, restore the latest differential backup.
F.
Restore the latest full backup. Then, restore each differential backup taken before the time of
failure from the most recent full backup.
G.
Perform a page restore.
H.
Perform a partial restore.
I think E is the correct answer here.
The correct answer should be C. Differential backup is not required, because the latest Differential backup would be done at 13:00 hours previous day. You will have the latest full backup at mid night (1:00) and after that there is no latest differential backup, since it fails at mid day 13:00.
“The differential backup of the reporting database fails.” This means only Full backup is available and ‘C’ is the answer.
The most recent backup of the reporting database is the 01:00 Full Backup since the 13:00 Differential Backup failed. So the answer is (C). In the real world, you might also run the data update task manually since users will be expecting data to be refreshed as of the 12:30 scheduled run, but this has been rolled back.
I am continually browsing online for articles that can benefit me. Thx!
